- Frequent Questions
- Where do I find the updated table 11.19.2-1, Emission Factors for Crushed Stone Processing Operations?
Can't find your question here? Contact the Info CHIEF Help Desk at email@example.com
At the time the section was made final some additional QA work was expected
on test reports that would allow us to publish the total particulate emission
factors. You can find the results of the total particulate tests in the
Chapter 11.19.2 Background Document.
The test data are as good if not better than many we use for other emission
factors. However, industry and some state agencies have expressed their
uncertainty of the data.
Contact Info CHIEF, for more information.
